MAIN BANG SUPPRESSION SETTING

Main Bang Suppression is adjusted to suppress main bang, a reflection signal
from a 3D circuit including wave guide tube, which generally appears as a circular
image focusing on the center of the radar display. Optimum adjustment allows
main bang image to be dimly lit on the display.
This adjustment is made for settings in the processing circuit of the display unit.
